The Rubrics of the Missale Romanum 1962

XIV. Those things done if the Priest celebrates twice or thrice in the same day

1. The Priest who celebrates
two or three Masses without interruption on Christmas or All Souls Day,
that is, when he leaves the Altar, does the following:

a) In the first and second
Masses, if he is to celebrate another immediately, having consumed the
divine Blood, neither purifies nor wipes the Chalice, but places it
upon the Corporal and covers it with the Pall. Then with his hands
joined he says Quod ore sumpsimus, and washes his fingers in a vessel of water, saying Corpus tuum, Domine,
and wipes them. After this, the Chalice, as yet remaining on the
Corporal, he places aside and covers again in the normal manner, that
is, with the Purificator, then the Paten with the Host to be
consecrated, and the Pall, and then the Veil. The Chalice should not be
placed outside the Corporal. If he inadvertantly drinks the ablutions
with the wine, he can nevertheless celebrate the second and third
Masses even before three hours have passed, if necessary. He completes
the other Mass as usual.

b) In
the second and third Masses, if another Mass has been celebrated
immediately beforehand, having removed the Veil at the Offertory, he
places the Chalice toward the Epistle side for a little while, but
within the Corporal. After offering the Host, the Chalice is not wiped
with the Purificator, but leaving it within the Corporal, raises it
slightly, pours the water and wine into it, and without wiping it
within, offers it. All else is done as usual.

2. If
the priest is to celebrate more Masses with an interruption, he should
perform the two ablutions prescribed by the rubrics. If the following
Mass is to be celebrated before the passing of three hours, water only
should be used in the ablutions. If he inadvertently drinks the wine,
he may nevertheless celebrate the following Mass before the passing of
three hours, if necessary.
